Perked up my mower engine
Appear to be legit. Gapping looked correct. Worked and my Kawasaki 22 hp definitely running smoother now. Replaced old NGKs with many hours on them.

What can you say more than these are pretty much the gold standard for spark plugs. These particular ones were well packaged and perform great.

Awesome choice in spark plugs
When it comes to sparkplug NGK has no competition. Be the application small or large engines I've found this brand to be far superior to all others. I've literally run into situations where I've installed other brands and they simply didn't provide enough spark for the engine to run properly and only replacement of the new plugs in it NGKs remedied the problem. They are certainly competively priced and available almost anywhere plus are available. Good maintence practices almost always call for plug replacement among other components, I've found noticqble improvement when I replaced the plugs while other components brought only piece of mind.
